Toward a vision system for blinds

摘要

This paper addresses design principles and definition of a non-invasive vision system assisting blinds in their dispalcements in non-cooperating environment. The global environment perception and understanding is a key problem for scuch systems. The optical vision is one of sense providing the global information on nearest environment; its association with conventient global enviroment representation transmittred to blinds via tactile interface allows blinds to locate all moving and flexed obstacles. Adding vision sensor to electronic travel aid (ETA) for blinds increase blinds autonomy, ehpos them to orient and move in safety in 3D envionrment. The announced principles for vision-based ETA can be easily transposed to any robotics, and especially humanoids, vision system.
